To @ZZ flo/wm t may concern: l

Be it known that l, HENRY llSoHorr, a citizen of the United States, residing' at River Forest, in the county of Cook and State of Illinois, have invented a new and useful AutoA Lock,v of which the following` is a specification.

ri`his invention has, reference` to motor vehicle locks and aimsto-provide novel means associated with the` intake manifold of a motor to restrict the passage of fuel from the carburetor to the cylinders of the motor. l

Anvobject of the` invention is to provide :a device of this character including pivoted -closures adapted to be controlled from the operators seat, whereby the operator may prevent the passage of fuel through the intake manifold of a motor.

A further object of the invention is to provide means for automatically returning the closure to its open position after the lock associated with the device has been actuated to unlock the device, thereby insuring against the closure remaining `in its vclosed position. Y

With .the foregoing and other objects in view, which will appear' as the description proceeds, the invention 'resides in the combination and arrangement of parts and in the detailsl of construction hereinafter described and claimed, 'it being understood that changes in theiprecise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing' from the spirit of the invention. v

- Referring' to the. drawings Figure l is an elevational view disclosing' the relation between the lock on the instrument board vand lock positioned in the intake manifold.

F igure 2' is a perspectiveview of the lock positioned Yinthe intake manifold, the cover thereof being removed.`

Figure 3 is an elevational view of the lock used on the instrument board, the cover thereof being removed.

Figure 4i is an elevational view of the lock positioned on ythe instrument board disclosing the mechanism thereof in its unlocking position. A e

Figure is a bottom .plan view of the cover.

Serial No. 609,986.

Figure 6 is a sectional view taken on line 6 being provided to receive the usual `con! nectinp,` bolts employed atgthis point. o

Formed integral with the plate is a boxlike structure indicated at Twhich'is pro# vided with a cover not shown', and which houses the mechanism employed for Aoperat- :ingthe closures or valve` sections designed to'control the passage fluid throughthe intake manifold.. 1 ,A

As shown an opening- Sis formed in the plate 5, the opening being circular in for- V.mation and of a diameter equal to the diameter of the usual intake pipe fof a manifold so that the walls of the openin j form continuations of the intake pipe iperating' within the opening' vare the segmental closures or valve members), each of which is supportedon a shaft l0, the shafts being positioned in suitable openings inlthe wall providing' bearings for 'the'shafts These shaftsV extend'beyond onewallk of the box-like structure 7 and are supplied with pinions il which are in inesh,'so that movement of one shaft will result in a rela" tive movement of the adjacent shaft. 'One of these shafts is of a length greater than the opposed shaft where the same supports the depending' arm 'l2 there being,` provided a spring' member Vlfd coiled around this' extensionv4 and associate-l with the arnr l2 in such a way as to cause thea-rin l2 `to move to a position as shown by Figure-Zot the drawings, after the mechanism has been operated to release the arm, in a Amanner to be hereinafter more fully described. l

Movable through the 'box-likev structure is a sliding block 14 that moves between the pin 14 securedfto the bottom wall of the box-like structurel and extends upwardly to engave the member 14 and provide a guide therefor. :This block extendsupv Wardly to Contact with the arm 12 when the same is moved longitudinally of the box- Y likestructure 7 to;aecomplisli theoperatioi'i A slot 15 is formed iny the block 14, which slot has an enlarged end i portion 16 to accommodate the screw 1T of the shafts 10.

when the block 14 has been moved a predetermined distancein the box-like .strncture 7 as Yby means oi? an instrument forced Within the box-likey structure-to operate. the block, thereby ,permittinp;k the .block to 'tall -positionbehind the' shoulder 19 vat one end of the plate 20, and prevent reverse-movement of: the block it'gbeing LindenV stood Vthat the spring-member to be herel inafter more 'tally described, is of suiiicient that YWhen-the-blockqinember 14 is released,

, theV spring 22 `r`will return the Ysa-me *to its normal 'for inactive Y:position asshown by Figure-f2 ot-theldra-Wings.

Ylt lrnigzght 'be further 'stated however ythat Athe-Strnctnre ojthe members -9jis such asf-to Vcompletely close the' opening 8 when they havebeen lmoved to their Yactive positions,

lthereby cutting off the passage' of fuel thronghtheintake manifold.

Y An openingindicated ,at 23 is provided in oneend' of the vbox-like structure, the Wall thereof Vbeinw'threaded 'to accommodate lthe' vthreaded vend of the pipe 24, through Which the controlli-ngvvvire 25 moves.' @ne kend 0 1 vthe controlling Wire has connection withthe block 14 as at '26 so that movement of the controllingVV Wirewill result in a movey ment of the -block- 14.

Associatedywith Vthe pipe 24 is 4a pipe 27 which is of kless diameter than the pipe 524 `to permit the same tomove or 'telescope Within the vpipe 24, thereby adapting the device orusefin connectionwith automobiles off various sizes, it being Vobvious that by moving- `the pipes 24and 2'? lWith respect to each athen-the lengthsof Vthepipes maybe variedrf/.he -npper Vend of the-pipe '27g-is 'threaded and is positioned-in a V suitable openingin ythe flange28 formed `integral with the plate 29 providing lthe vbase, of the locking mechaa guideway :tor the movable actuating'block 31.

The controlling rod 25 has connection' with this block 31 as zatlf'ivhereby upon movement or' the block 31, the Wire 25 is Yalso operated to accomplish the Ymovement or the/bleek 14andfparts associated there- 1 'fr' laterally extending; lug indicated at 38 is formed on the block Stand is designed t0 Contact .vitlrthelingers 84 and 35 carried on the shaift o the usual lock struotnreto accomplish the 'moving ot`the controlling,`
